Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Nematicity with a twist: Rotational symmetry breaking in a moiré superlattice [PDF]

open access: yesScience Advances, 2019
Twisted 2D materials realize a unique electronic nematic state, quite different from its counterpart in bulk quantum materials. Motivated by recent reports of nematic order in twisted bilayer graphene (TBG), we investigate the impact of the triangular ...

Single Pair of Weyl Points Evolve From Spin Group‐Protected Nodal Line in Half‐Metallic Ferromagnet V3S4

open access: yesAdvanced Functional Materials, EarlyView.
A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

On the relationship between gauge dependence and IR divergences in the ℏ-expansion of the effective potential

open access: yesJournal of High Energy Physics, 2019
Perturbative calculations of the effective potential evaluated at a broken minimum, V min, are plagued by difficulties. It is hard to get a finite and gauge invariant result for V min.

Symmetric Gapped Interfaces of SPT and SET States: Systematic Constructions

open access: yesPhysical Review X, 2018
Symmetry-protected topological (SPT) states have boundary ’t Hooft anomalies that obstruct the effective boundary theory realized in its own dimension with UV completion and with an on-site G-symmetry.
